As the world mourns the victims of Volgograd, Russians and non-Russians alike must brace themselves for more—and bloodier—terror attacks in Russia, including during the Olympics next month. Moscow would be well served by expanding its security cooperation with countries that have a good track record of foiling terror attacks. The Sochi 2014 Olympics will include 6,000 Olympic athletes and team members from 85 countries. Hosting such an event is a remarkable undertaking for any nation. Therefore, the U.S. should assist the Russian leadership and Olympic council to put in place comprehensive counterterrorism measures to protect the city of Sochi, the athletes, and the spectators while allowing an exciting and competitive global event to take place.
